The SEI electronics wiring diagrams were recently updated.

Models were modified to reflect those changes on our Units:
HAM2-ISI
HAM3-ISI
HAM1-HEPI
HAM2-HEPI
HAM3-HEPI

Models were recompiled and wiring was checked. IPS readouts match values recorded prior to re-wiring. Turning sensor's interface chassis on/off is reflected on the correct channels. Actuation was checked on HAM3-ISI, confirming the DAC number for HAM2-ISI (only 2 DACs on HAM23 IO chassis).

Damping loops, and level 2 Isolation loops were closed, on HAM3-ISI. We used the latest blend filters created during the IMC test. Controls were not tested after the vent. The current stability of these controllers confirms both the new wiring/models and the robustness of the control loops, in Air.

Hence, these control loops will be used to help IO locking the mode cleaner during the upcoming weeks.
